An auto-bonding robot (ABR) that consists of the mechanism of adhesive dispensing and auto-bonding, a pneumatic system and a control system, is presented in this paper. It is designed for the bonding operation of cover-glasses and space solar cells using adhesives. An adhesive dispensing method is proposed to control the thickness and position of the adhesive layer on solar cells and to provide a satisfactory bonding accuracy. The bubble-free bonding process is realized by the leaning mechanism of a pneumatic sucker. Experimental comparison of the manual and automatic bonding methods showed that there are no fragment and air bubbles between the cover-glass and the space solar cell, and no outflow adhesive on the surface by the automatic bonding process in a non-vacuum condition. The novel automatic bonding robot greatly improved the lightweight space solar cells bonding quality and production rate.

At present, adhesive coating is by far the most widely used technique in the space panel manufacturing. The automatic process level is essential for improving the quality and efficiency of the space solar cell array assembly. In this study, the surface coating model for adhesive dispensing on the space solar cells is obtained, which describes the relationship between the thickness of the adhesive layer on the solar cell, the moving speed of the syringe and the differential pressure. Then the structure of the surface coating robot is presented for the space solar cell arrays assembly. The experimental results have showed that the surface coating robot can greatly improve the efficiency and quality of the space solar cells array assembly. The adhesive no longer outflows and stains the solar cells and the panel. This robot is useful to protect the environment and keep workers away from the poisonous chemicals. Instead of the manual work in space solar cell arrays assembly, the application of the surface coating robot will enhance the development of space industry.

SUMMARYThis paper discusses about auto-laydown robot (ALR), which is applied to performing the laydown process of a solar module on earth. The robot consists of an adhesive dispensing mechanism, an auto-laydown mechanism, a pneumatic system and a control system. The method of gripping solar cells is described based on pneumatic technology. Meanwhile, a new method of controlling adhesive thickness and area during dispensing is proposed in this paper. The robot realizes the automatic laydown process of solar modules and can control the laydown pressure effectively. Compared with the manual method, the robot could control the dispensing volume and the adhesive area between solar modules and panel substrates, by means of experiments. The novel ALR greatly improves the laydown quality of solar modules and meets the lightweight trend of solar cells development.

Adhesive sandwich structures with the honeycomb core of the metallic foil, polymeric papers and composites are widely and effectively used in the units of aerospace engineering and in the other industries owing to a number of undeniable advantages, including high specific strength and stiffness. In the process of designing and manufacturing of abovementioned structures, it is necessary to ensure high strength and reliability of the adhesive joint of the bearing skins and honeycomb core at a small area of their contact. The decisive factors influencing the bearing capacity of such joint are the technological parameters of the bonding process. Using the finite element modeling, the paper deals with the bearing capacity of the adhesive joint of bearing skins with the honeycomb core based on the aluminium foil and polymeric paper Nomex at transversal tearing for the key factors of the bonding process. The pattern of the adhesive joint failure (on the adhesive of honeycombs) has been revealed, depending on the depth of penetration of honeycombs ends in the adhesive, physical and mechanical characteristics of honeycombs, modulus of elasticity and tearing strength of the adhesive and thickness of the adhesive layer. Peculiar features of behavior of adhesive joints of the bearing skins with the honeycomb core based on the aluminium foil and polymeric paper Nomex under the load have been established, which should be taken into account in designing and manufacturing of honeycomb structures. The recommendations are given with regard to choosing of parameters of the process of honeycomb structure bonding, which allow providing with the acceptable accuracy the optimal depth of penetration of ends of the honeycomb core faces in the adhesive layer of specified depth.

Efficiency Enhancement

This paper presents the efficiency enhancement for a novel photovoltaic/thermal (PVT) air collector in which PV and thermal efficiency is simultaneously enhanced with a reciprocal aid. With the encapsulation of solar cells directly on a fin-type heat sink, the direct conduction mechanism and the convective area for the thermal transportation are effectively increased. Through a two-month experiment measurement, it is found that the thermal efficiency of PVT module is obviously enhanced up to over 50% in sunny days. In addition, the waste heat recovery decreases the operating temperature of solar cells and concurrently improves the PV efficiency. The results demonstrate the concurrent enhancement of the novel PVT module in PV electricity and solar thermal efficiency.

Abstract More than a million times every year, an ambulance is deployed in the Netherlands. Of these instances, 87% of the patients will be administered intravenous (IV) fluids. In the current situation, the IV bag always needs to be held above the patient to function properly. This action requires an extra pair of hands, which is very inefficient and can result in the loss of precious time that could otherwise be directed at the patient. Besides needing an extra pair of hands, there is also a chance of air bubbles entering the patient through the drip feed. The novel drip chamber design proposed in this paper aims to solve these problems, as it enables the IV bag to be placed in any orientation and in any manner relative to the patient with a negligible number of air bubbles entering the drip feed. This novel drip chamber was tested in an experimental setting in different orientations and at different flowrates. From the test results, it can be concluded that at a clinical relevant flowrate, a negligible number of air bubbles were present within the IV system. Because of the ease of use of the novel drip chamber and the fact that it is fool-proof, cost-efficient, and shows promising test results, future research on several aspects could make this product a promising addition to health care.
